MANIFOLD STRAINER FOR CLOTH WASHERS.

Application filed December 16, 1926. Serial No. 155,298.

This invention relates to what are known as cloth washers such as are used in textile mills for washing lengths or cuts of cloth.

These washers include a tank in which are squeeze rolls between which pass relatively long strips of cloth each having its ends sewed together.

There are generally four, six or eight such endless strips or string of cloth and they are kept separate by a rake shaped guide.

The mode of operation is to introduce into the tank a relatively small amount of warm water to which liquid soap is added, whereb when the squeeze rolls are started, the clot passes many times through the soapy water and then through the squeeze rolls, the result being a washing of the cloth.

After this has continued a suflicient length of time, an outlet in the bottom of the tank is opened and the soa y water is allowed to run out. As the cloth is still saturated with soap however, the outlet is then closed, certain gates are opened, and others are closed and a large quantity of clean warm water is mtroduce'd into the washer and directed upon the cloth through nozzles. A trough or suds box positioned under the squeeze rolls and connected with an outlet controlled by one of said gates, is brought into action to carry off the soapy water squeezed from the cloth when passing through the rolls. This operation is continued until all trace of soap has disappeared from the cloth.

Often 10,000 to 15,000 gallons of clean water heated to about 110 degrees Fahrenheit are directed on the cloth for an hour or two hours before vthe cloth is sufficiently freed from soap.

In using such machines, it is found that a vary small amount of dirt or rust such as is usually present in any water supply which runs through pipes of any character, if allowed to come in contact with the cloth, will, after it has passed through the squeeze rolls, be spread out and forced into the material to such an extent that a great deal if not the whole piece is made practically worthless.

To successfully use a washer of this kind however, the clean water supply must come in very freely and it is difficult to provide a strainer of such character that it will keep out the dirt and rust but at the same time allow a sufficiently free flow of water.

My device includes a manifold having a number of inlet nozzles which enter the tank, each provided with a cylindrical strainer whereby the total straining surface is a great many times larger than the area of the water supply pipe and of the nozzles.

In the drawings, Fig. 1 is a side elevation of a cloth washer of the type to which my device is applicable, equipped with my device, part being broken away to show the interior COIlStlllCtlOIl.

Fig. 2 is an elevation from the right of Fig. 1.

Fig. 3 is an enlarged section on line 3-3 of Fig. 1, viewed from the top.

Fi 4 is a reduced section on line 44 of Fig. 3.

Fig. 5 is an end View of a strainer head and a clamp arm swung away from it.

Fig. 6 shows a flat nozzle.

In the drawings, A is a tank having an outside casing represented by 10, inside of which are the squeeze rolls R and L.

R is a roll carried by the shaft 60 slidable vertically in slots such as 11, 11, while L is carried by shaft 61 which carries at one end the gear 62 in engagement with the gear 63 on one end of shaft 60.

Shaft 61 also carried a gear 64 in engagement with a gear 65 carried on counter shaft 66 driven by a pulley 67 from any source of power.

H represents an inlet pipe through which either hot or cold water can be passed into the manifold G.

M is an outlet pipe controlled'by handle 62 and gate 61.

K is a trough or suds box located under the bottom squeeze roll L provided with suitable outlets and 53 controlled by gate 51, whereby it will conduct water to the outside of the machine at 53, or will allow it to run back into the bottom of the tank through 'holes 50 to be reused.

Gate 51 has cross passages 54 which may register with trough holes 50 allowing the soapy water to run through when the end of gate 51 blocks outlet 53, or to close holes 50 when'the end of gate 51 opens outlet 53. This construction is old.

-G re resents a manifold which is preferably of Square cross section and is carried by the brackets B, B, fastened to the casing 10 of tank A.

68 represents what might be called a rake sha ed ide which consists of a number of vstic s suitably ositioned inside the tank to keep separate t' e' strands of cloth such as T.

Positioned preferably below and between each two sticks of this guide 68 midway between it and the bottom are inlet holes 16 in the wall 10 of tank A, and into these holes fit nozzles 21 extending from the manifold G.

On the inside of each nozzle 21 is an annular groove 24 into which fits the open end 30 of a cylindrical strainer F.

Each of these strainers F includes the fine wire mesh screen 34 which is fastened to an annular shoulder 32 of a head 33.

The diameter of this cylinder is such that it can pass in through a strainer hole 22 opposite a nozzle 21, and each head 33 is larger than this strainer hole whereb it makes a tight joint along the trued up e ge 23 of each hole 22.

Each strainer is substantially in the form of a cartridge shell.

Between each two strainers F, F, is a clamp screw G which passes through a clamping bar 42, each end of which rests on a head 33, screw C having a collar 41 on its shank 40 whereby by tightening or loosening clamping screw C, the bar 42 will hold two strainers F in place, or it can be swung around so that any two of them may instantly be removed.

While the first process of washing is going on, these cartridge shaped strainers F can be removed and thoroughly cleaned by introducing from the open end 30, high pressure steam. This passes out through in the opposite direction to that in which the water comes in, thereby forcing out any particles of dirt or rust.

Preferably each strainer head 33"has on its inside an annular shoulder 35, around which a gasket U may be used. This shoulder 35 preferably fits snugly into strainer hole 22. Inside shoulder 35 is another annular shoulder 32 of smaller diameter and around this fits the cylindrical screen 34.

At the open end 30 is a ring 37 preferably chamfered on one side at 38 to help direct the open end into groove 24 and on its other side an annular shoulder 39, around which fits the other end of screen 34. 37 closely fits groove 24.

Head 33, ring 37, and screen 34 are preferably of brass as are also the rods 70, 70, 70, 70, which connect the head and ring and hold the strainer F in shape. I
